“…Apparently, this is a common disadvantage of colorimetric detection methods, and similar results can be seen in the published literature. 38–40 To eliminate the effects of the above three kinds of interfering substances, corresponding measures should be adopted, for example, by adding masking agents 41 or they should be further separated by combining with other precision techniques (such as high-performance liquid chromatography), etc . Therefore, this is also an opportunity and challenge for colorimetric detection analysis methods.…”

“…The MnO 2 could shield the short-wavelength upconversion fluorescence without affecting near-infrared fluorescence, which realizes the ratio sensing based on GSH. Besides, various configurations of MnO 2 nanostructures are also used to develop GSH activated procedures, such as MnO 2 nanoparticles, honeycomb MnO 2 , , , MnO 2 nanosheets, , MnO 2 nanowires, and so on. Hence, MnO 2 nanomaterials provide diversified programs to construct an off–on fluorescence sensing strategy for highly sensitive monitoring of GSH.…”

Herein, we report an activatable multifunctional nanocomposite (denoted as FSMP) for glutathione (GSH) sensing and synergistic theragnostics to cancer cells. This novel core–shell architecture orderly consists of a fluorescein isothiocyanate-doped SiO2 core, a methylene blue (MB)-encapsulated porous MnO2 shell, and poly(ethylene glycol) for shielding the MB from premature leaking. The fluorescence of the core will be effectively quenched by MnO2 due to the Förster resonance energy transfer, and the quenched signals could be recovered in the presence of GSH, as a result of the reduction of MnO2 to Mn2+. The constructed GSH sensing nanoplatform shows stable response to GSH in a linear range of 10–300 μM with the limit of detection of 2.1 μM. Besides acting as a fluorescence quencher and a GSH recognizer, MnO2 also serves as a sequence self-reinforcing Fenton nanoagent based on the GSH sensing to form Mn2+, which exerts the activity to generate •OH from H2O2. Further, combined with the MB-mediated photodynamic 1O2 generation, the multifunctional nanocomposite jointly produces an enhanced therapeutic effect. In addition, FSMP will be degraded within 48 h, thus significantly reducing the potential nanotoxicity. We believe the MnO2-nanomaterial-based sequence strategy could potentially improve biochemical analysis and cancer cell theragnostics applications.

Nanozymes, next‐generation enzyme‐mimicking nanomaterials, have entered an era of rational design; among them, Co‐based nanozymes have emerged as captivating players over times. Co‐based nanozymes were developed and have garnered significant attention over the past five years. Their extraordinary properties, including regulatable enzymatic activity, stability, and multifunctionality stemming from magnetic properties, photothermal conversion effects, cavitation effects, and relaxation efficiency, have made Co‐based nanozymes a rising star. This review presents the first comprehensive profiling of the Co‐based nanozymes in the chemistry, biology, and environmental sciences. The review begins by scrutinizing the various synthetic methods employed for Co‐based nanozyme fabrication, such as template and sol‐gel methods, highlighting their distinctive merits from a chemical standpoint. Furthermore, we provide a detailed exploration of their wide‐ranging applications in biosensing and biomedical therapeutics, as well as their contributions to environmental monitoring and remediation. Notably, drawing inspiration from state‐of‐the‐art techniques such as omics, a comprehensive analysis of Co‐based nanozymes is undertaken, employing analogous statistical methodologies to provide valuable guidance. To conclude, we present a comprehensive outlook on the challenges and prospects for Co‐based nanozymes, spanning from microscopic physicochemical mechanisms to macroscopic clinical translational applications.This article is protected by copyright.
